Description

Technical Field

[0001] This application relates to the technical field of automated powder box processing equipment, and in particular to a nailing machine for powder boxes. Background Technology

[0002] As a crucial component of cosmetic packaging, the assembly quality of powder compacts directly impacts the user experience and aesthetic appeal of the product. During assembly, the top cover and inner shell are typically hinged together using metal nails or pins to create an openable structure. Therefore, powder compact nailing machines are key pieces of equipment in mass production.

[0003] In the existing technology, the powder box nailing machine adopts a symmetrical dual-station structure design. The nailing machine includes two of the core components such as the mounting plate, fixed support plate, slide bar, rotating fixing component, slide bar fixing block, nail pusher, vibrating nail barrel, and first telescopic rod, which are distributed on both sides of the vertical central axis in the top view of the nailing table. This provides a structural basis for improving processing efficiency to a certain extent. However, due to the limited number of vibrating nail barrels and the nail supply logic, it can only nail one powder box at a time in actual processing, and cannot fully realize the high-efficiency processing potential of the dual-station structure.

[0004] With the continued growth in demand for powder compacts in the beauty market, manufacturers are increasingly demanding higher processing efficiency. The existing single-powder-box nailing process using existing nailing machines is gradually failing to meet the efficiency requirements of mass production. Within the same production timeframe, the total number of nails that can be nailed is limited, resulting in a slow overall production pace that struggles to keep pace with downstream supply chain delivery cycles. Furthermore, some manufacturers are forced to compensate for the insufficient efficiency of individual machines by increasing equipment investment or extending production hours to boost output. This not only increases equipment procurement and factory space costs but may also accelerate equipment wear and tear due to prolonged continuous production, leading to higher maintenance costs and product defect rates. Utility Model Content

[0005] In view of the above-mentioned prior art, in order to solve the problem that although the existing powder box nailing machine has a dual-station structure, it can only nail one powder box at a time due to the limitation of the number of vibrating nail barrels and the nail supply logic, resulting in low efficiency of powder box mass production, this application provides a nailing machine for powder boxes.

[0006] This application provides a nailing machine for powder boxes, which adopts the following technical solution: A nailing machine for powder boxes includes a worktable, a feeding assembly, and a nailing assembly. The worktable has two symmetrically arranged and spaced-apart powder box molds, each mold having a limiting groove for fixing and limiting the powder box. A support plate is provided on the worktable corresponding to one side of the powder box mold. The feeding assembly includes a vibrating nail barrel, a slide bar, and a driving component. A first sliding groove is provided on the top of the support plate, the slide bar is slidably fitted into the first sliding groove, and the driving component drives the slide bar to slide along the first sliding groove. Two inlet holes are provided on the side wall of the support plate away from the powder box mold, and two outlet holes are provided on the side wall of the support plate near the powder box mold. Two storage holes are provided on the side wall of the slide bar. Two vibrating nail barrels are provided, and both barrels are fixedly installed on the worktable and... The material end is connected to two feed through holes. When the slide bar is in the initial position, the feed through hole is connected to the storage through hole. When the slide bar is in the processing position, the storage through hole is connected to the discharge through hole. The two powder box molds have connecting holes on their side walls near the support plate. The two discharge through holes are connected to the connecting holes on the two powder box molds one by one. The connecting holes are connected to the limiting grooves of the powder box molds. The nailing assembly includes two push nails and a pusher. The two push nails are located on the side of the support plate away from the powder box mold. The support plate has through holes for the push nails to pass through. The through holes are connected to the first slide groove and correspond one-to-one with the discharge through holes. The pusher is fixedly installed on the worktable. One end of the push nail is located in the through hole, and the other end of the push nail is connected to the pusher.

[0007] By adopting the above technical solution, the slide bar can reciprocate between the initial position and the processing position under the drive of the drive component. The initial position completes the reception of nail material from the vibrating nail barrel to the storage through hole. The processing position aligns the storage through hole, the discharge through hole and the powder box mold connecting hole to form a nailing channel. The nail pusher pin accurately drives the nail material into the powder box under the action of the pusher component, realizing the time separation and precise coordination of the nail supply and nailing actions.

[0008] Preferably, a fixing block is provided on the workbench corresponding to the powder box mold, a second sliding groove is provided on the top of the fixing block, a slider is provided on the top of the powder box mold for sliding and cooperating with the second sliding groove, and a fixing component is also provided on the fixing block for fixing the position of the powder box mold.

[0009] By adopting the above technical solution, the position of the powder box mold on the worktable can be flexibly adjusted through the cooperation of the slider and the second slide groove. When nailing different powder boxes (top cover and inner shell), different specifications of powder box molds can be changed through the second slide groove and fixing parts, enabling the equipment to quickly adapt to various product specifications and enhancing the versatility and flexibility of the equipment. At the same time, this structure ensures the stability of the mold during the nailing process, avoiding the impact of nailing accuracy due to positional displacement. This facilitates mold replacement and adjustment and ensures consistent positioning in mass production.

[0010] Preferably, the worktable is provided with a sliding member for the pusher to slide. The sliding member consists of two sliding shafts. One end of each sliding shaft along its length is fixedly connected to a support plate. A sliding shaft fixing block is provided at the end of each sliding shaft away from the support plate. The sliding shaft fixing block is fixedly installed on the worktable. A sliding block is slidably mounted on each of the two sliding shafts. The pusher is mounted on the top of the sliding block. A limiting member is provided on the sliding block to lock its position on the sliding shaft.

[0011] By adopting the above technical solution, the sliding block can drive the pusher to move along the sliding shaft, which makes it easy to adjust the initial position of the pusher to adapt to different nailing depths or powder box models; the limiting component can ensure that the position of the pusher is fixed during nailing, ensuring the accurate transmission direction of the nailing force and avoiding deviation.

[0012] Preferably, the pushing component is a pushing cylinder, and the end of the telescopic rod of the pushing cylinder is provided with a connecting plate, and the ends of the two push pins away from the support plate are fixedly installed on the connecting plate.

[0013] By adopting the above technical solution, using a cylinder as the power source, the action response is fast and the thrust is stable; by simultaneously driving two push pins through the connecting plate, the coordination of the synchronous driving of the two nails is ensured, and the structure is simple and reliable.

[0014] Preferably, the fixing component is a threaded fixing rod, the powder box mold is provided with a threaded connecting block, the threaded connecting block is provided with a through hole, the side wall of the fixing block is provided with a threaded connecting hole, and the threaded connecting rod is adapted to the threaded connecting hole; when the powder box mold is installed on the fixing block, the threaded connecting block abuts against the side wall of the fixing block, and the threaded connecting hole is connected to the through hole on the threaded connecting hole.

[0015] By adopting the above technical solution, mechanical locking is achieved through threaded fixing rods, resulting in a firm connection, good vibration resistance, and convenient disassembly and assembly, which facilitates mold replacement and maintenance.

[0016] Preferably, the limiting member is a locking screw, and a threaded hole is provided on the side wall of the sliding block. One end of the locking screw is threadedly connected to the threaded hole. When the locking screw is tightened, one end of the locking screw abuts against the sliding shaft.

[0017] By adopting the above technical solution, the locking screw generates axial preload through the threaded pair, directly abutting against the surface of the sliding shaft, and achieving reliable locking by using friction. The structure is compact, easy to adjust, and the locking force is adjustable.

[0018] Preferably, there are two of each of the support plate, feeding assembly, and nailing assembly, which are symmetrically arranged on both sides of the vertical central axis of the workbench in the top view direction.

[0019] By adopting the above technical solution, a symmetrical dual-station processing structure is formed. The two stations can independently complete material feeding and nailing operations, and can simultaneously nail two powder boxes. Compared with the traditional single-station processing mode, this significantly improves nailing efficiency per unit time, effectively adapting to the needs of mass production of powder boxes and reducing equipment investment and factory space occupancy costs. At the same time, the symmetrical layout of the dual stations ensures more balanced force distribution on the worktable, reducing wear and tear caused by concentrated force on one side of the equipment and extending its service life. Furthermore, when one station experiences a temporary malfunction or requires mold replacement, the other station can continue operating, reducing production interruption time, ensuring stable overall production rhythm, and further improving production continuity and overall capacity.

[0020] In summary, this application includes at least one of the following beneficial technical effects: 1. By setting up reciprocating sliding rails and symmetrically arranged double sets of feeding and nailing actuators, true synchronous and continuous nailing operations at both workstations are achieved, significantly improving the mass production efficiency of powder boxes; 2. The position of the powder box mold is adjustable and can be firmly locked. The position of the nailing component can also be finely adjusted and locked, which enhances the equipment's adaptability to powder boxes of different specifications and improves the flexibility and precision of processing. 3. The slide bar can reciprocate between the initial position and the processing position under the drive of the drive component. The initial position completes the reception of nail material from the vibrating nail barrel to the storage through hole. The processing position aligns the storage through hole, the discharge through hole and the powder box mold connecting hole to form a nailing channel. The nail pusher pin accurately drives the nail material into the powder box under the action of the pusher component, realizing the timing separation and precise coordination of nail supply and nailing actions.

[0023] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0024] This application discloses a nailing machine for powder boxes.

[0025] Reference Figure 1 A nailing machine for powder boxes includes a workbench 1, a feeding assembly 2, and a nailing assembly 3. Two powder box molds 4 are installed on the vertical central axis of the workbench 1 in a top view. The two powder box molds 4 are symmetrical and spaced apart. The powder box molds 4 are provided with limiting grooves 41 for fixing the powder box molds 4. Two sets of feeding assemblies 2 and nailing assemblies 3 are respectively provided and are located on both sides of the vertical central axis of the workbench 1 in a top view. The feeding assembly 2 is used to transport nails to the powder box molds 4, and the nailing assembly 3 is used to drive the nails into the powder box.

[0026] Reference Figure 2 Specifically, the workbench 1 is provided with two symmetrical support plates 5, which are located on both sides of the vertical central axis of the workbench 1 in the top view direction. Two powder box molds 4 are located between the two support plates 5. The feeding assembly 2 includes a slide bar 21 and a driving component 22. A first groove 51 is formed on the top surface of the support plate 5 along its length. The slide bar 21 is slidably installed in the first groove 51. The driving component 22 is fixedly installed at one end of the support plate 5 along its length and is used to drive the slide bar 21 to slide along the length of the first groove 51. (Refer to...) Figure 3 and Figure 4The support plate 5 has two feeding holes 52 on the side away from the powder box mold 4, and two discharging holes 53 on the side wall of the support plate 5 near the powder box mold 4. The feeding holes 52 and the discharging holes 53 are respectively connected to the first slide groove 51. The slide bar 21 has two storage holes 211 through the side wall. When the slide bar 21 is in the initial position, the feeding holes 52 are connected to the storage holes 211 on the slide bar 21. When the driving member 22 drives the slide bar 21 to the processing position, the storage holes 211 are not connected to the feeding holes 52, but are connected to the discharging holes 53. The two powder box molds 4 have connecting holes 42 on the side walls near the two support plates 5. The connecting holes 42 are connected to the limiting grooves 41 on the powder box mold 4. In this embodiment, the driving member 22 is a driving cylinder, and one end of the slide bar 21 along the length direction is fixedly connected to the extension end of the driving cylinder.

[0027] The feeding assembly 2 also includes two vibrating nail barrels 23. The two vibrating nail barrels 23 are fixedly installed on the side of the support plate 5 away from the powder box mold 4. The two vibrating nail barrels 23 are respectively provided with conveying pipes 6 between them and the support plate 5. One end of the conveying pipe 6 is connected to the feed hole 52 on the support plate 5, and the end of the conveying pipe 6 away from the feed hole 52 is connected to the discharge end of the vibrating nail barrel 23.

[0028] When feeding, the drive unit 22 drives the slide bar 21 to slide to the initial position, so that the feed through hole 52 is connected to the storage through hole 211. The nails in the vibrating nail barrel 23 enter the storage through hole 211 through the conveying pipe 6 and the feed through hole 52, thus completing the feeding process of the nails.

[0029] Reference Figure 1 and Figure 5 The specific nailing assembly 3 includes two push pins 31 and a pusher 32. The support plate 5 has two through holes on the side facing away from the powder box mold 4. These two through holes are connected to the first sliding groove 51 on the support plate 5 and correspond one-to-one with the two discharge through holes 53. When the drive member 22 drives the slide bar 21 to the processing position, the through holes, the storage through hole 211, and the discharge through hole 53 are connected. The pusher 32 is a push cylinder 321, located on the side of the support plate 5 facing away from the powder box mold 4 and slidably mounted on the worktable 1. The telescopic rod of the push cylinder 321 is fixedly mounted with a connecting plate 7. One end of the push pin 31 is located inside the through hole, and the end of the push pin 31 away from the through hole is fixedly connected to the connecting plate 7.

[0030] When nailing is performed, the drive unit 22 drives the slide bar 21 to slide to the processing position, so that the material storage through hole 211 is connected to the material discharge through hole 53 and the through hole; the cylinder 321 is pushed to move, which drives the nail pusher 31 through the through hole on the support plate 5, and pushes the nail located in the material storage through hole 211 into the designated position of the powder box through the material discharge through hole 53 and the connecting hole 42, thus completing the nailing operation.

[0031] The workbench 1 is provided with a sliding member 8 for the cylinder 321 to slide. The sliding member 8 consists of two parallel sliding shafts 81. One end of each sliding shaft 81 along its length is fixedly connected to the support plate 5. A sliding shaft fixing block 9 is fixedly installed on the end of each sliding shaft 81 away from the support plate 5. The sliding shaft fixing block 9 is fixedly installed on the bottom side of the workbench 1. A sliding block 10 is slidably arranged on the two sliding shafts 81. The bottom of the sliding block 10 is provided with a sliding groove 101 corresponding to the two sliding shafts 81. The sliding block 10 is slidably arranged on the sliding shaft 81 through the sliding groove 101. The cylinder 321 is fixedly installed on the top of the sliding block 10. A limiting member 11 is provided on the sliding block 10 to lock the position of the sliding block 10 on the sliding shaft 81.

[0032] The limiting component 11 is a locking screw 111. A threaded hole 102 is provided on the side wall of the sliding block 10, which is connected to the first sliding groove 51. One end of the locking screw 111 is threadedly connected to the threaded hole 102. When the locking screw 111 is tightened, the locking screw 111 abuts against the sliding shaft 81 to lock the sliding block 10 along the sliding shaft 81. Through the threaded locking screw 111, the sliding block 10 can be precisely fine-tuned. Its end directly abuts against the sliding shaft 81, which can generate strong friction, thereby reliably locking the sliding block 10 at any desired position on the sliding shaft 81.

[0033] Reference Figure 6 Specifically, a fixing block 12 is provided on the workbench 1 for each powder box mold 4. A second sliding groove 121 is provided on the top of the fixing block 12, and a slider 43 is provided on the bottom of the powder box mold 4 to slide along the fixing block 12, allowing the powder box mold 4 to slide along the fixing block 12. To lock the position of the powder box mold 4, a fixing member 13 is provided on the fixing block 12 for fixing the powder box position. The fixing member 13 is a threaded fixing rod 131, and a threaded connection hole 122 is provided on the side wall of the fixing block 12. A threaded connection block 14 with a through hole is provided on the bottom surface of the powder box mold 4. When the powder box mold 4 slides to the target position, its threaded connection block 14 abuts against the side wall of the fixing block 12. At this time, the threaded fixing rod 131 passes through the through hole and is screwed into the threaded connection hole 122, thereby firmly fixing the powder box mold 4.

[0034] When nailing the top cover and inner shell of the powder box, the powder box workpiece is first clamped in the mold limiting groove 41 fixed to the worktable 1. At this time, the slide bar 21 is in the initial position, and its material storage through hole 211 is connected to the feed through hole 52 of the vibrating nail barrel 23 to receive nail material. Then, the drive component 22 drives the slide bar 21 to the processing position, so that the material storage through hole 211, the discharge through hole 53 on the support plate 5 and the connecting hole 42 on the powder box mold 4 are aligned to form a nail material channel. At this time, the push cylinder 321 of the nailing component 3 is activated, driving the nail pusher 31 to pass through the support plate 5 and accurately push the nail in the material storage through hole 211 into the hinge hole of the powder box to complete the nailing. Finally, all the execution components are reset, and the finished product can be unloaded. With two sets of symmetrically arranged feeding and nailing components, the machine can perform nailing operations on two powder boxes simultaneously, thereby achieving high-efficiency and continuous production.

[0035] The implementation principle of this application embodiment is as follows: By symmetrically arranging two independent feeding and nailing components 3 on both sides of the central axis of the workbench 1, and cooperating with the laterally sliding slide bar 21 structure, synchronous nail feeding and synchronous nailing at two workstations are realized. The slide bar 21 reciprocates between the initial position and the processing position under the action of the driving component 22, respectively completing the receiving and delivery of nail material; when the slide bar 21 is in the processing position, the nail pusher 31, driven by the pushing component 32, continuously pushes the nail material into the hinge part of the powder box. This structure effectively utilizes the potential of the dual-mold layout, allowing the nailing operation of two powder boxes to be performed simultaneously, thereby significantly improving the continuous operation efficiency and production cycle of the equipment.

[0036] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
